PAUL A. BREDSVOLD, OF ST. LOUIS, MISSOURI.

LIGHTING-FIXTURE.

To all whom it may concern:

Be it known that I, PAUL A. BREnsvoLo, a citizen of the United States of America, re-

.sicling at the city of St, Louis, State of Missouri, have invented a certain new and useful Lighting-Fixturd of which the following is such a full, clear, and exact description as will enable any one skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a lighting fixture and consists in-various novel features and details of construction, all of which will be described in the annexed specification and pointedout in the. appended claims.

In the accompanying drawings, which illustrate one form of fixture made in accordance with my invention, Figure l is aside view, partly in section and partly in elevation; Fig. 2 is a top plan view, some of the parts being removed; Fig. 3, is a section on the line 3 casing being removed; Fig. is a section on the line 4'L of Fig. 2; and Figs. 5, 6 and struction.

Like marks of reference refer to similar parts in the several views of the drawings. 10 represents the supporting member which is connected by means of a threaded .pipe 11 with a bracket consisting of two parts 12 and 13 respectively, as best shown three in number,

in Fig. 1. Secured to this bracket by means of screws 1% is a socket l 5 of any usual form for supporting an electric lamp bulb 16. The lower part of the bracket 13 is provided with an up-turned portion 17 upon the face of which are formed lugs 18, preferably Secured to these lugs 18 by means of screws 19 is .areflector "20 of the formbest shown in F ig. 5. This reflector 20 has a central opening 21 for the passage of the lamp bulb l6 and said opening is slightlylarger than the lamp bulb in order to allow for the passage of heated air between the two members. Arranged within the lugs 1 is a deflector 22 between which 'and the reflector 20 the heated air is allowed flector 20 and the deflector 22,1 provide .an

Specification of Letters Patent.

Application filed January 2, 1914. Serial No. 809,832.

annular screen 23. The outer edge of the reflector 20 is provided with an upwardly extending flange 21 which is provided with slots 25, preferably threein number, for the passage of pins 9.6 carried by an annular frame 27. The flange 2% isalso preferably provided, adjacent to the slots 25, with re cesses 28 into which the pins26 may rest after the annular member .27 has been slightly rotated. Below the'reflector 20 is a second reflector 30 which, like the reflector 90, is provided with a central opening for the passage of the bulb 16, said opening being of sufficient size to allow for the passage of heated air between the bulb and the refiector. The reflector 20 is secured to the reflector 30 by means of a number of plates 31 which also form partitions dividing the reflector into a pluralityof compartments,

preferably six in number. 3lmay be secured to the reflectors in any suitable manner, but I prefer to provide said partitions with lugs '32 adapted tov pass through slots in the reflectors and be bent over, as best shown in Figs. 5 and 6. The annular member 27 is provided with a plurality of openings corresponding innumber The partitions from. the lower part of the annular member '27 by means of an outwardly projecting flange 37 resting upon the inwardly projecting flange 38 carried by'the said member. The lower face of the reflector 30 is adapted to intercept any rays of light which might tend to pass upwardly from the-bowl 36,"

thus preventing the crossing of light rays in the compartments formed by the partitions 31. The bottom of the bowl 3 6 is provided with an opening for the admission of air and this opening has secured in ita screen 39 to prevent the entrance of dirt or nsects, as best shown in Fig. l of the drawfi ht: operation of myfixture will be evident. -The light from the lamp 16 is directedlloutwardly by the reflectors 20 and and also by the partitions 31 which also act as reflectors, and is directed in the various holllowisprdtrudin shades 33. The lower surface of the re ector 30 also serves to reflect the light downwardly through the bowl 36 and thus prevent the crossing of light rays inthe'compartments. The heated air which surroundsthe bulb 16 may pass up between said bulb and the reflectors 20 and 30 and then pass outwardly between the reflector 2D,,and the' deflector 22. When it isdesired toireplace the lamp 16, or to clean the parts, 1t; isf necessary onlyto rotate the annular naember l27 soflthat the pins 26 may pass downwardly-through the slots 25. In this way, the: said member, togetherwith the "bowl 36v and-shades 33 carried thereby, is

' renroied'fromzthe remainder of the fixture.

This gives access to'the device and thereby allojvs the parts" 3 3 and 36- to be cleaned as the'se arts-can be entirely removed from themem .cr.

Having fully described my device, what raising-aw and'desire to secure by Letters' Patent of the United States is l; a lighting fixture, the combination with a source of light, of a' support'for said light, and a reflector divided into a plural ity 0t compartments, said compartments being arranged side by :side in-the direction of the circumference'of the fixture.
